A study of the N to Delta transition form factors in full QCD

TL;DR

This paper investigates the N to Delta transition form factors in full QCD using lattice simulations with dynamical MILC configurations and domain wall fermions, comparing unquenched and quenched results across different pion masses.

Contribution

It provides new unquenched lattice QCD calculations of N to Delta transition form factors at multiple pion masses, improving understanding of baryon structure.

Findings

Unquenched results differ from quenched at similar pion masses.

Form factors GM1, GE2, GC2 are evaluated at three pion masses.

Results contribute to more accurate baryon transition models.

Abstract

The N to Delta transition form factors GM1, GE2 and GC2 are evaluated using dynamical MILC configurations and valence domain wall fermions at three values of quark mass corresponding to pion mass 606 MeV, 502 MeV and 364 MeV on lattices of spatial size $20^3$ and $28^3$. The unquenched results are compared to those obtained at similar pion mass in the quenched theory.
